I'm going out of town and need someone to walk my senior maltipoo Nina at 7:30a, 3p, and 9:30p. She wears a diaper and will need it put back on if not heavily soiled after each walk. She's 16 years old but is very friendly and gets the zoomies at walk time. My mom will be home but she's too elderly to walk Nina. I just walk her around the neighborhood and let her sniff things and potty--each walk is 30 minutes.
